The 2014 Chevy SS is no shrinking violet out of the box as it is, capable of 13.3 seconds at 107.6 mph according to our compatriots at Motor Trend. That’s faster than any Impala SS from the golden age of performance (think L72 427). And 1.5 seconds faster with the HPE600 package? Back then, that would require enough equipment to render an Impala SS unstreetable.
